Question

If a line has an x-intercept at =

3 and a y-intercept at y = – 5, find its equation in the form
y = mx + b.
y

Answer 1

y = 5/3x - 5

Explanation:

y = mx + b

b = y-intercept

m = slope

y = mx - 5

plug in the x-intercept

0 = m(3) - 5

5 = 3m

m = 5/3

y = 5/3x - 5

graph is below, both intercepts are on the line
